What the cooling-off period is in NSW
NSW Fair Trading’s description, in substance: when you buy a residential property by private treaty in NSW, you have a cooling-off period of 5 business days after exchange of contracts, during which you can withdraw from the contract. If you do, you forfeit 0.25% of the purchase price to the vendor. The period does not apply if you buy at auction, and it can be waived, shortened or extended. The authoritative wording, and any change to it after this guide was written, is on the NSW Government cooling-off period page. Read that page; treat this one as the inspector’s explanation of how to use the time.
Why does it exist? Because in NSW you exchange first and inspect second, at least in the common private-treaty sequence. An accepted offer is not binding until contracts are exchanged, and once exchanged you are bound. The cooling-off period is the legislature’s answer to the obvious problem with that: it gives you a short, priced window to find out what you have bought and change your mind.
When the clock starts and stops
- It starts as soon as contracts are exchanged. Not when your offer is accepted, not when you pay the holding deposit: at exchange.
- It ends at 5pm on the 5th business day after the day of exchange. Exchange on a Monday and, with no public holiday in the way, the period ends at 5pm on the following Monday.
- Business days exclude weekends and NSW public holidays. Exchange on the Thursday before Easter and the arithmetic changes; your conveyancer counts it, and it is worth asking them to state the exact date and time in writing the day you exchange.
One trap worth naming because a ranking page gets it wrong: the period runs from exchange, not from when you first agreed the price. If a page tells you otherwise, trust Fair Trading.
What it costs to walk away
0.25% of the purchase price, paid to the vendor. On a $800,000 property that is $2,000; on $1,000,000 it is $2,500; on $1,500,000 it is $3,750. That is arithmetic, not law, and what happens to the rest of your deposit before and after the period is a question for your conveyancer. The reason the number matters here is comparison: the inspection fee is a fraction of it, and the repair bill on a house with live termites or a moving footing is a multiple of it. The inspection is what tells you which house you are buying before the 0.25% becomes a discount on a mistake.
When there is no cooling-off period
| Situation | What NSW Fair Trading says | What it means for the inspection |
|---|---|---|
| Buying at auction | No cooling-off period applies. | Inspect before auction day. The report is your only window. |
| Same-day exchange after passing in | If the property is passed in at auction and you exchange on the same day, no cooling-off period applies. | Same as auction: the inspection happens before the day. |
| A 66W certificate | Your solicitor or conveyancer can sign a certificate under section 66W of the Conveyancing Act waiving the cooling-off period. | Irreversible, with the deposit at stake. Whether to sign one is a conveyancer decision; if you do, inspect before exchange. |
| Reduced by agreement | The period can be shortened by written agreement with the vendor. | Ask your conveyancer what was agreed and when the shortened period ends. |
On the 66W certificate: vendors and agents sometimes ask for one to make an offer “unconditional” and competitive. It removes your window entirely. Whether to sign it is not an inspection question and we will not answer it; it is the single most consequential decision in the sequence and it belongs with your conveyancer. What we will say is that if you are signing one, the inspection must happen before exchange, not after.
Buying off the plan: 10 business days
Off-the-plan contracts in NSW carry a 10-business-day cooling-off period rather than 5, per Fair Trading. There is no finished house to inspect at exchange, so the inspection question moves to the end of the build: a stage or handover inspection before you accept the keys, and the statutory warranty period after. Anything else about off-the-plan contracts (sunset clauses, disclosure, the deposit) is your conveyancer’s territory.
How to fit a building and pest inspection inside 5 business days
This is the canonical version of the plan; every other page on this site links here rather than repeating it. It works because the report arrives the same day, which leaves days, not hours, to decide.
- Day 0
Exchange
The clock starts. Ask your conveyancer for the exact end date and time in writing. Call us the same day, or before, and say you're in cooling-off.
- Day 1 to 3
The inspection
Structure and timber pests in 1 visit. Same-day service is available for cooling-off period inspections. Call and say so, and we'll tell you the soonest we can be there.
- Same day
The report
Photographed, with major and minor separated. Read it, then talk to the inspector who was on site about anything that is not clear.
- Before 5pm, day 5
The decision
Proceed, renegotiate, ask for an extension, or rescind. Each is a conversation with your conveyancer, with the report in hand.
The failure mode is booking on day 3 with an inspector who reports in 3 business days. Do the arithmetic on the day you exchange, and if the dates do not work, tell your conveyancer before the period ends rather than after.

What to do if the report finds a major defect
You have 3 options inside the period, and all 3 are decisions your conveyancer makes with you, not ones the inspector makes for you.
- Renegotiate. A photographed, rated finding with a plain note on what it is and which specialist would quote the fix is a specific ask, not a vague worry. The vendor is not obliged to agree to anything; your conveyancer handles the conversation.
- Ask for an extension, in writing.If you need an engineer’s opinion or a treatment quote and the period will not stretch to it, the period can be extended by written agreement with the vendor. Your conveyancer asks; the vendor can say no.
- Rescind before 5pm on day 5.How, to whom and by when the notice must be served is a legal procedure with a deadline, and your conveyancer does it. Meena Ahn, in her review: “Swift and proactive with their communication and organising the building inspections. Reports were completed very quickly, and what I received was very clear, precise, and thorough. I was able to make my property purchase decisions with confidence (I rescinded on one based on their report), and gave me more points for my negotiations for my new one.”
Waiving, shortening or extending the period
All 3 are conveyancer conversations, not inspector ones. What the inspection changes is the information you take into them: a clean report makes a shortened period tolerable; a report with a major finding is the reason to ask for more time. If you are asked to sign a 66W certificate, our only contribution is that the inspection then has to happen before exchange, and we can usually make that work if you call early.
Questions to take to your conveyancer
- What is the exact date and time my cooling-off period ends, allowing for public holidays?
- Has this contract varied the standard period, or written in an inspection or finance clause?
- What happens to my deposit if I rescind inside the period, and after it?
- If I am asked to sign a 66W certificate, what am I giving up, and is there any way back?
- If the report finds a major defect, how do we ask for an extension, and how is a rescission notice served?
- Is this an off-the-plan contract, and if so, what does the 10-day period and the rest of the contract mean for me?
The timing decision that comes before all of this (inspect before the offer, after it, or inside the period) is the before or after the offer guide. What the inspection actually covers is the covers guide, and what it costs relative to the 0.25% is the cost page.
